Abstract

PROCEDIMIENTO PARA LA OBTENCION O RECUPERACION DE ACIDOS, EN PARTICULAR ACIDO CLORHIDRICO, ACIDO FLUORHIDRICO Y ACIDO NITRICO, A PARTIR DE SOLUCIONES DE ESTOS ACIDOS QUE CONTIENEN METALES, POR TRATAMIENTO PIROHIDROLITICO Y A CONTINUACION ABSORCION Y/O CONDENSACION DE LOS GASES FORMADOS EN UNA SOLUCION ACUOSA DE ABSORCION, RETIRANDO LOS COMPUESTOS SOLIDOS QUE APARECEN. PARA GARANTIZAR UNA RECUPERACION ECONOMICA DEL ACIDO, EN INSTALACIONES YA EXISTENTES Y SIN GRANDES MEDIDAS DE ADAPTACION, EL LIQUIDO RESIDUAL DE DECAPADO SE SOMETE A UNA PRECONCENTRACION POR EVAPORACION ANTES DE LA PIROHIDROLISIS UTILIZANDO EL CALOR DEL GAS DE SALIDA DE LA PIROHIDROLISIS. EN UN DISPOSITIVO PARA LA OBTENCION O RECUPERACION DE ACIDOS, EN PARTICULAR ACIDO CLORHIDRICO, ACIDO FLUORHIDRICO Y ACIDO NITRICO A PARTIR DE SOLUCIONES DE ESTOS ACIDOS QUE CONTIENEN METALES, COMPRENDIENDO UNA ENTRADA DE LA SOLUCION, UN REACTOR DE PIROHIDROLISIS, Y AL MENOS UNA COLUMNA DE ABSORCION O CONDENSACION, QUE ESTA UNIDA CON LA SALIDADE GAS DEL REACTOR, SE PREVE PARA LA PREEVAPORACION Y CONCENTRACION DE LA SOLUCION UNA INSTALACION 1, 3, 4; 31,32.PROCEDURE FOR OBTAINING OR RECOVERY OF ACIDS, IN PARTICULAR CHLORHYDRIC ACID, FLUORHYDIC ACID AND NITRIC ACID, FROM SOLUTIONS OF THESE ACIDS CONTAINING METALS, THROUGH PIROHYDROLYTIC TREATMENT AND CONTINUED FORMATION OR SOLUTION ABSORPTION, WITHDRAWING THE SOLID COMPOUNDS THAT APPEAR. TO GUARANTEE AN ECONOMIC RECOVERY OF THE ACID, IN ALREADY EXISTING FACILITIES AND WITHOUT GREAT ADAPTATION MEASURES, THE RESIDUAL LIQUID OF DECAPING IS SUBMITTED TO AN EVAPORATION PRECONCENTRATION BEFORE THE PIROHIDROLISIS USING THE HEAT OF THE GAS HEAT. IN A DEVICE FOR THE OBTAINING OR RECOVERY OF ACIDS, IN PARTICULAR CHLORID HYDRAULIC ACID, FLUORHYDIC ACID AND NITRIC ACID FROM SOLUTIONS OF THESE ACIDS CONTAINING METALS, UNDERSTANDING AN ENTRY OF COLORING A COLLECTION, A COLLECTION OF A COLLECTION, A COLLECTION ABSORPTION OR CONDENSATION, WHICH IS UNITED WITH THE GAS HEALTH OF THE REACTOR, IS PROVIDED FOR PREEVAPORATION AND CONCENTRATION OF THE SOLUTION AN INSTALLATION 1, 3, 4; 31.32.
